Borg, be careful if you are selling on eBay. I wouldn't recommend sending anything you can't get insured on. Lots of scammers out there that will either say they did not receive your package of you sent tracked, will say that they still never received it and that is not their signature. You will then be forced to issue a refund. Insurance is vital for that extra security. I personally never do an auction but a fixed price with a best offer option.
Unfortunately, eBay will always side with the buyer and not seller. Always look at the profile of the person interested in your items and go on from there. I've only had a couple of problems when I've actually purchased something and it hasn't come. I received my refund after disputing. Thankfully no problems as of yet when selling anything.
